Currently, systemd uses 90s as the default mount unit timeout, in some cases, although it works well in 1st kernel, it's not enough under kdump and results in mount timeout, further results in kdump dumping failure.
We've met several such issues, we decided to enlarge this default value a little for kdump.
We finalize "x-systemd.device-timeout=300" as the default timeout to the mount options if there is no "x-systemd.device-timeout=X" specified. It can be overridden by /etc/fstab mount options,etc, so that users can specify other timeout values if they want to.
Note: this is different from rd.timeout which was introduced by dracut initqueue.

v1->v2: -Use 300s other than 600s as the default value.
